ASTRO: Animation of Crab using Chandra Xray, Radio, Optical and emission line images

There is a neat image of the Crab made using Radio=Red, Optical = Green and
XRAY = Blue he

I took the image, rotated it and stretched it to overlay my recently
reported crab shot with emission line filters where [SII] = Red, Ha = Green
and [OIII] = Blue

Once I did that I decided to animate a morphing between the two images. It
is sort of interesting to watch the various structures transform. Some
completely disappear or reappear, while others just transform their color
and or shape.

Warning: this was my first animation. I used Adobe Image Ready. For some
reason it makes the image sort of grainy. Maybe I can figure out how to fix
it. If anyone has some suggestions for addressing the graininess or has
other ideas
of how to do the morphing/animation, please tell me!

here is a link to the file on my website. It is about 2.2MB.
